research overview

  • Prof. Gasiewski is an internationally-recognized expert in passive and active remote sensing of atmospheric and oceanographic processes, and contributor to several related underlying disciplines, including electromagnetic wave propagation, scattering, and radiative transfer theory, signal detection, estimation, and model-based data assimilation, microwave instrumentation, and sensor calibration and metrology. He is actively engaged in the development of surface-based, airborne, and spaceborne remote and in situ sensing systems for meteorology, hydrology, climatology and related environmental applications. His specific interests include the development of UAS-based systems for Earth observation and a geostationary passive microwave imaging system for improved mesoscale weather forecasting. He also has interests in radar systems for glacial ice imaging, environmental sensor systems for renewable energy development, and systems for sensing electrical phenomena in the atmosphere.
